WebStorm provides facilities to run CSS-specific code quality inspections through integration with the Stylelint code verification tool. The tool registers itself as a WebStorm code inspection: it checks CSS code for most common mistakes and discrepancies without running the application. When a tool is activated, it launches automatically on the edited CSS file. Discrepancies are highlighted and reported in pop-up information windows, a pop-up window appears when you hover the mouse pointer over a stripe in the Validation sidebar. You can also press Alt+Enter to examine errors and apply suggested quick fixes. Learn more about inspections and intention actions at Code Inspection and Intention Actions.
